Estado, burguesía e legislação trabalhista brasileira no limiar dos anos 30: notas para uma discussão

The creation and implementation of Brazilian labor laws during the 1930s gave rise to important political debates. The various stakeholders - the state, the bourgeoisie, and workers - each with their own social project, had forged mechanisms designed to protect their own interests. Within this framework, this article addresses the arguments regarding the Expulsion of Foreigners Act (1907), the "Dois Tercos"(Two-thirds) Act (1930), and the Unionization Act (1931). These acts provide clear evidence that the growth of state interventionism was accompanied by tensions and changes, and that the labor legislation was not simply the 'gift' of a Corporate State.

A Educação Musical Brasileira e Três Modelos Explicativos de Mundo: em busca de significados

In this paper we study the main modalities of music education in Brazil and how they can be compared to different views worldwide. Recognition that modern practices in music education are inserted in contemporary knowledge paradigms shows their relevance to a changing world. According to this contemporary paradigm the practices included herein point to alternatives in the relationship between men and themselves, men and other men and men and the environment. They also encourage cooperation, the relationship among the arts, the conduction of actions ruled by the principles of ecology and the recovery of values lost or weakened.

Mosca-Negra-dos-Citros: Características Gerais, Bioecologia e Métodos de Controle dessa Importante Praga Quarentenária da Citricultura Brasileira

Citrus blackfly, Aleurocanthus woglumi Ashby, is a serious pest of citrus culture and other economically important fruit crops. It is a present quarantine pest or A2 maximum alert restricting trades with other regions free of its presence. Since the frst occurrence of the citrus blackfly in Belem in 2001 its dissemination was quickly to other States and regions of citrus production in Brazil. As an exotic pest, basic knowledge is scarce in order to establish the appropriate management to the insect in Brazil. Thus, the aim of the present study was to provide information about important aspects of A. woglumi, such as: history and geographical distribution, bioecology, host plants, appropriate control methods, among others, in order to provide subsidies for futures researches about the citrus blackfly in Brazil.

Tinea nigra: Relato de caso e revisao da literatura brasileira

The authors present a clinical case of palmar Tinea nigra in a 19-year-old young woman. The Brazilian literature concerning Tinea nigra is discussed as well as the reports presented in Brazilian Congresses from 1985 to 1995. The data show that 63.3% of the cases occurred in patients younger than 20-years-old, they were more frequent among females and 90.5% were localized on the palms; among the cases reported in the Brazilian Congresses those of atypical localization as the back and the genital area are worth noticing.

Efeito de auxinas e boro no enraizamento de estacas caulinares de kiwi retiradas em diferentes épocas

This work was carried out to study the effects of some synthetical auxins and boron on the rooting of stem cuttings of kiwi (Actinidia deliciosa Pl. cv. Tomuri). Cuttings of semi-woody stems with two knots and leaves divided in two, with approximately 10 cm of length were utilized. The base of the cuttings received the following treatments: 1) water only; 2) NAA 300 ppm; 3) IBA 300 ppm; 4) NAA 300 ppm + B; 5) IBA 300 ppm + B; 6) NAA 0,5%-talc and 7) IBA 0,5%-talc. After these treatments, the stems were placed in suitable rooting dishes, with pure vermiculite in misty nebulization chamber for 120 days. Evaluations were made based on the following observations: percentage of rooted stem cuttings; reductor sugar and total sugar analyses and tryptophan analyses. The results showed that the autumm season is the best for rooting for kiwi stem cuttings. The exogenous application of 0.5% of IBA talc on the bases of the cuttings showed positive results.

Estudo quantitativo da lágrima pelo teste de fenol vermelho na população brasileira

Purpose: To detect normal values of red phenol thread test in the Brazilian population and compare it between different races, age and sex. Methods: 280 white individuals (560 eyes) and 280 non-white individuals (560 eyes) were analyzed regarding sex and age, and analyzed using the Phenol Red test. Individuals with ocular diseases, contact lens or ocular drug users were excluded from this study. Results: Of the 1,120 evaluated eyes, the mean ± standard deviation result was 19,77±7,90 mm. Conclusion: The mean result found in this study was an intermediate value compared to the previously studied populations (Japanese and American).

Correcão ionosférica utilizando os MAPAS: Globais do TEC DO IGS: Avaliação no posicionamento por ponto na região brasileira

One of the main drawbacks of the GPS accuracy for L1 users is the error due to ionosphere. This error depends on the total electron content presents in the ionosphere, as well as of the carrier frequency. Some models have been developed to correct GPS observables of the systematic error due to the ionosphere. The model more known and used is the Klobuchar model, which corrected 50-60% of the ionospheric error approximately. Alternatively, IGS (International GNSS Service) also has developed a model called Global Ionospheric Map (GIM). These maps, in format IONEX, are available in the site of the IGS, and one of the applications of them is to correct the GPS observables of the error due to ionosphere. This work aims at evaluating the quality of GPS point positioning using the IGS ionospheric model in the Brazilian region. Tests carried out had shown an average improvement in the horizontal and vertical determination of 72% and 26%, respectively, when GIM is used in the point positioning.

Fontes de distorções da rede geodésica Brasileira

The Brazilian Geodetic Network started to be established in the early 40's, employing classical surveying methods, such as triangulation and trilateration. With the introduction of satellite positioning systems, such as TRANSIT and GPS, that network was densified. That data was adjusted by employing a variety of methods, yielding distortions in the network that need to be understood. In this work, we analyze and interpret study cases in an attempt to understand the distortions in the Brazilian network. For each case, we performed the network adjustment employing the GHOST software suite. The results show that the distortion is least sensitive to the removal of invar baselines in the classical network. The network would be more affected by the inexistence of Laplace stations and Doppler control points, with differences up to 4.5 m.
